“Your menstrual cycle could become longer

Umbrella
What may the Perimenopausal Bleeding Umbrella include?
Depending on the Source (DotS) this Umbrella may include:
- Abnormal Uterine Bleeding (AUB)
- Perimenopausal Bleeding/Menstrual Cycle
Perimenopause
What is perimenopause?
DotS the definition of perimenopause may vary. In Menopause: Key Facts the World Health Organization’s definition is:
- “The menopausal transition can be gradual, usually beginning with changes in the menstrual cycle. Perimenopause refers to the period from when these signs are first observed and ends one year after the final menstrual period”.2
Perimenopause Periods
What may perimenopause periods be like?
In Menopause: How Do Your Know If You’ve Reached Perimenopause? the (Australian) Jean Hailes for Women’s Health (JH) explain:
- Irregular
- Shorter or longer than usual
- Lighter or heavier than usual
- Absent for a few months”.3
Period Pattern
During perimenopause, do most women have a fairly consistent period pattern?
In Perimenopause: Abnormal Uterine Bleeding the Menopause Society (formerly the North American Menopause Society) explain:
“What is considered a normal menstrual cycle varies greatly from woman to woman. Still, in the years approaching perimenopause, most women will have a pattern that’s fairly consistent, so any changes in their bleeding pattern may be noticeable. To determine whether these changes are of concern, it is important that a woman consults with a healthcare professional. Keep in mind that it can be useful to track the bleeding on a calendar or smartphone app so that it can be easily reviewed and assessed”.4
Menstrual Calendar
Where may I find a menstrual calendar to keep a record of perimenopausal bleeding?
In MenoNotes the Menopause Society include the menstrual calendars:
Menstrual Calendars
PMS

Health Care Provider
What if I think I have perimenopausal bleeding?

- Periods that are much heavier than usual
- Spotting or bleeding between periods
- Periods that last longer than 10 days
- Bleeding after sex
- Frequent periods (fewer than 21 days between periods)
- Any bleeding after menopause”.6
In Perimenopause: Symptoms and Causes – How Can I Reduce My Risk of Perimenopause Complications? the Cleveland Clinic elaborate on:
- Your periods become very heavy or contain large blood clots
- You change pads or tampons every one to two hours
- Your periods last several days longer than usual
- You spot or bleed between periods
- You bleed after sex
- Your periods occur less than 21 days apart”.7
In Periods: When To See Your Doctor About Your Periods the JH explain:
- Heavy periods
- Painful periods
- Absent periods
- Unusual bleeding (e.g. bleeding between periods, after having sex or after menopause)”.8
